LB11851M Datasheet (Sanyo Semicon Device)

LB11851M, Monolithic Digital IC

Ordering number : ENA0673A Monolithic Digital IC LB11851M Overview www.DataSheet4U.com Microprocessor Fan Motor Interface Driver The LB11851M provides an interface between a microcontroller motor control signal and external MOS transistors.

This device can implement a microprocessor fan driver with a minimal number of external components.

The LB11851M is optimal for server and personal computer microprocessor fan drive in response to temperature or other external signals when high precision

LB11851M Features

* Fan motor interface driver function (FGIN) ⇒ This IC accepts a signal from a microcontroller and interfaces to external power transistors (PMOS and NMOS) to provide high-efficiency low-power single-phase full-wave drive.

* Variable speed input pin (PWMIN) ⇒ PMOS side PWM control NM
